Supplies food for (6)
I believe the answer is:
caters
'supplies food for' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for caters that I've seen before include "provides what's needed" , "Provides for in crates" , "Provides services for, supplies" , "Provides what is needed, say food and drink" , "Supplies food for parties" .)
